Maven pom systemProperty path to file syntax

Have follwong chunk from pom.xml:

<systemProperty>
    <name>axis2.config</name&开发者_如何学Cgt;
    <value>file:${project.build.directory}/../../axis2.properties</value>
</systemProperty>

what does syntax for value tag mean?

/../ - is id cd .. and forwards to parent directory?

short: ../ means parent direcory

long version:

• file: specifies, that the following content should be interpreted as a file path.
• ${project.build.directory} is a variable which will be replaced by the runtime with the actual project build directory
• / are folder separators
• .. means parent folder
• axis2.properties is the name of the properties file

if you want to display the path for debugging purposes you might want to have a look at this:

or

maven ant echoproperties task

Yes, it's a relative path to the project build directory, and go upper (in parent) two times.

In other words: it's the parent directory of the directory that contain your project build directory ;)
